OEM DETROIT RELIABILT Reman DDE R5237650 Series 60 DDEC 2/3/4 11.1/12.7/14.0L "Stage 1" InjectorThe 7650 injector is a great fit for the every day work horse and works great for anything in the 400 650hp range. This injector was a factory offering in the BK Premium model 12. 7 Detroit. Since this model has the newer style 9 hole nozzle providing a finer fuel atomization than a comparable 8 hole injector, this is a great choice for most Series 60 enthusiasts looking for a clean burn and a significant power upgrade over OEM low hp model injectors.
